I was trying to replace the head light on my 41', which may have 46' buckets on it. One of the 2 tension springs, for setting beam angle was broken, and I broke the other - pretty rusty. I ordered new ones from Jim Carter, but can't figure out how to get the old remnants off, or how the new might fasten to the base assembly. Anyone know where I can get a diagram, or can give me some insight. I don't want to take off the bucket if I don't have to.
